SPINNING- OR TWIS TIN G APPARATUS.

Specification of Letters Patent.

Patented Oct. 6, 1908.

Application filed March 9, 1908. Serial No. 419,870.

To all whom it may concern:

Be it known that I, ALoNzo E. RHoAnEs, a citizen of the United States, and resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Spinning or Twisting Apparatus, of which the following description, connection with the accompanying drawing, is a specification, like letters'on the drawing representing like parts.

This invention relates to apparatus for spinning or twisting yarn wherein the yarn is traversed upon the, bobbins by the vertical reciprocations of a ring-rail, governed by what is technically termed the buildermotion. I

The builder-motion comprises a rocking arm actuated by a traverse-cam, and a winding mechanism mounted on the arm and connected with the ring-rail by means including a flexible member or chain, which is gradually and automatically let-ofi by the winding mechanism to effect the gain of the traverse, whereby at each up-stroke the ring-rail rises a little higher and ateach down-stroke descends not quite so low as on the previous down-stroke, laying the yarn in successive layers upon the bobbin from the lower end or butt to the upper end or tip.

As the chain is gradually unwound or let off from the drum of the winding mechanism during the operation of the apparatus it is necessary, after doffing a set of bobbins, to

\ wind-back before starting the winding of a fresh set, such winding-back consisting in manually rotating the drum in order to wind up the chain thereon to the starting position. The winding-back is usually performed by the attendant who applies a crank-like key or similar device to the winding mechanism, and the operation involves the expenditure of time and strength.

My present invention has for its object the production of means for effecting. windingback automatically, and herein I have shown such a construction and arrangement that the automatic winding-back is initiated by or through manual depression of the ringrail pre aratory to dofling.

As wi l a pear hereinafter the normal operation of t e spinning or twisting apparatus acts to set or place in condition for subsefication and particularly pointed out in the following claims.

Figure 1 is a front elevation of a portion of a spinning or twisting frame, showing the builder-motion and adjacent parts, and with one embodiment of my invention applied thereto, the ring-rail being shown in readiness to be depressed for dofiing; Fig. 2 is a view in inner side elevation of the parts at the left of the line 22, Fig. 1, the adjacent rocker being omitted for the sake of clearness of illustration; Fig. 3 is an enlarged sectional detail of a portionof the winding mechanism of the. builder-motion, to illustrate the construction whereby the windingback instrumentality is thrown into and out of control of the winding mechanism, the section being taken on the line 33, Fig. 2.

The s indle-rail 1 on which are mounted the spin les 2 shown in Figs. 1 and 2 as provided with filled bobbins 3; the vertically reciprocating ring-rail 4 provided with rings 5, one for each spindle, the lifter-rods, as 6, attached to the ring-rails; the rocker 7 cooperating with the foot of the lifter-rod, Fig. 1, and having a weight 8 to lift the ring-rail, and the rocker-arm 9 rigidly connected with the rocker and transmitting reciprocating movement to the other lifter rods (not shown) may be and are all of well-known or usual construction in spinning or twisting apparatus.

A chain or other flexible connection 10 is operatively connected at one end with the rocker, Fig. 1, and passes over a fixed guidesheave 11 down to the winding mechanism of the builder-motion, the latter acting through the chainlO to positively lower the ring-rail and permitting its ascent by the weight 8.

The builder-motion as herein shown comprises a builder-arm 12 having a fixed fulcrum 13, Fig. 2, and oscillated by the cooperation of a traverse-cam 14 with a roller or other stud 15 on the builder-arm, the weight 8 acting through the intervening connections to maintain the follower 15 in engagement with the actuating cam 14, .(shown herein as a fourpoint cam) the builder-arm having mounted upon it the winding mechanism, consisting essentially of a rotatable drum '16 around which the chain 10 is wound and to which its adjacent end is attached. The drum is acted upon by letting-off means during the Winding of the yarn upon a set of bobbins, to

gradually and positively rotate said drum and thereby let off the chain 10 little by little to-eifect the gain of the traverse.

Herein there are certain-novel features of construction and arrangement in the letting-- off means which I will describe indetail.

the gear.

Beyond the drum the hub has.

splined thereona clutch disk .20, having an, annular groove 2]., the teeth 22 of the clutch member vbeingadapted to cooperate withop posed teeth 23 on the adjacent end of the .drum, to connect the latter and the worm.

gear when the clutch, t. 42., the two sets of; teeth 22 and 23, :are in engagement so that unison.

be understood that the disk 20 can be moved .the drum and worm gear will then rotate in.

longitudinally on the hub 18 but is always,

rotatable therewith.

A depending bracket 25 fixed on the outer end of the stud 17 has fulcrumed upon it at.

26 a yoke 27 rovided with roller or other.

studs 28enter1ng the groove 21, a spring 29; being coiled around thestud 17 between the bracket 25 and a washer-like disk 30 resting against the outer face of the grooved clutchdisk 20, the spring acting to throw the clutch into operation.

The builder-arm 12 carries a worm-shaft 31 having a worm 32 in constant mesh with the worm-gear 19,.and a pick-wheel 33 is fast .on said shaft, a pawl 34 on a pawl-carrier 35 rocking on the shaft cooperating with the pick-wheel to rotatezthe shaft intermittingly, the pawl-carrier having a connected upturned link 36 slidable ina fixed guide 37 and provided with a stop-collar 38, so that on each down stroke of the builder-arm the colversely to the winding of the chain 10, the chain 39 being led upward from the drum over a fixed guide-sheave 40 and thence rearwardlyto and around. a second guide-sheave 41, Fig. 2, and down to an operating weight 42, as herein shown.

The weight and connected chain herein constitutes a winding-back instrumentality,

to rotate the drum 16 in such a direction that the chain 10 will be wound up thereon when it is desired to wind back the winding mechanism of the builder-.1notion,.as will be explained.

I have provided the yoke 27 with an arm 43 having a lateral lug 44 in-thepatho'l movement of .the depending leg 45 of a peculiarly shaped clutch-releaser, shown best in Fig. 1, and fulcrumed at 46 on a part of the main frame of the apparatus, said clutch releaser having a second depending leg 47 which has an edge 48 on an arc struckfrom the fulcrum of the rocker 7.

Viewing Fig. 2 it will be seen that the legs 45, 4-7 are laterally oilset and connected by a hub 49., the peculiar shapeof the cluteh-releaser being made necessary in-order that it shall clear various parts of the apparatusand the framing. The free end of the rocker 7 1 moves up and down close to the leg 47 and Thespline 24 is shown :in Fig. 3, and it will upon said rocker I fulcrum at 50, Fig. 1 .a manually operated depressing 111cm bershaped to present.a foot piece or treadle 51 and an 9 arm 52 havlng a rearwardly extended lug 53 crossing the curved edge 48 0f the leg 47, a stop 54 on the rocker limiting downwardrelative movement of the .treadle 51.

The normal vibration of the rocker .7 will cause the lug 53 to slide up and down along the curved edge of the leg 47 without causing any change in the clutch-releaser, while the winding mechanism is controlled by the letting-off means, and as the drum 16 is rotated to let ofi the ring-rail controlling chain 10 the chain 39 of the winding-back instrumentality will be wound up automatically, lifting theactuating weight 42.

In Figs. 1 and 2 it is supposed that the winding of a set of bobbins has been completed, the ring-rail being shown in its highest position, and in Fig. 2 the windingdmck actuator 42 is set, or in condition to operate.

Before dolling the operator depresses the ring-rail, and herein this is effected by plaeing the foot upon the treadle 51. and pushing it down onto the stop 54 and thereafter-(-ontinuing the downward pressure, to thereby depress the free end of the rocker .7 and lower the ring-rail to dol'ling position.

Vlhen the initial swing of the depressing member is ell'ected the lug 53 cooperates with the leg 47 and swings the clutch-releaser 45, 47 to the right, Fig. 1, to thereby swing the yoke 27 and disengage or render inoperative the clutch connection (the teeth 22, 23) between the winding drum and the letting-off means.

Obviously the drum, is thereby released from the control of the said letting-0d means and immediately the winding-back instrumentality assumes control of and operates to rotate the drum 16 and wind up the chain 10 as the descent of the weight 42 causes the chain 39 to unwind fromthe drum, it being remembered that the depression of the ringrail has slackened the connections between the winding mechanism and the ring-rail. The weight 42 is heavy enough to overcome friction and inertia of the parts, and the winding-back is quickly and effectively performed automatically. After the windingback is completed the release of the depressing member 51, 52 permits the clutch-releaser to return to normal position as the spring 29 expands and throws the clutch into operative condition. The winding mechanism is thereby released from control by the winding-back instrumentality and restored to the control of the letting-off means, the winding mechanism thereafter so controlling the winding-back instrumentality that the latter is set or placed in operative condition by the operation of the letting-off means actin" through the winding mechanism.
